Q: a sex therapist said he had seen a case of "penis injection" with 600 times, and there is no side effect anymore. I have used this method to treat impotence for most patients. Furthermore, with long-term application of this method, what should be paid more attention on when doing the injection, in order to ensure the safety.

Answer: the so-called "penile injections" refers to the intracavernous injection of vasoactive drugs, in the past by papaverine plus phentolamine injection, now with prostaglandin E1. The first injection is most applied by the doctor after execution, and then it can be performed by patients themselves. The method is simple, and the result can be immediate, applicable to any type of impotence. Although the impotence cannot be cured totally, but there are still many patients prefer this method.

When in use should pay attention to the following points:

(1) pay attention to strict disinfection;

(2) to determine the dosage, cannot arbitrarily change;

(3) the needle should be fine, the best selection of disposable syringe or using skin 4.25 skin test needle, furthermore needle has related to many side effects;
